Description

Technical Field

[0001] This utility model relates to a curtain wall technology, and more particularly to a curtain wall column and beam corner connection system that is adaptable to connections at different angles. Background Technology

[0002] As modern architectural forms increasingly trend towards irregular shapes and curved surfaces, curtain wall corner angles are becoming increasingly diverse. According to relevant statistics, irregularly shaped curtain walls account for as much as 37% of supertall buildings worldwide, with corner angles ranging from 30° to 150°. Typically, different angle ranges require corresponding specialized connectors and sub-frames at the front of the columns that match the angle's slope. This results in the inclusion of multiple types of connectors throughout the building, significantly increasing both material and installation costs.

[0003] For example, the "Curtain Wall Corner Connection Structure" disclosed in Chinese Utility Model Patent CN 212802176 U requires that the L-shaped connector be cut to an angle matching the included angle at the intersection of the longitudinal and transverse directions, so as to be inserted into the inner cavity of the horizontal beams on both sides, and then fixed to the middle column by a through bolt assembly. Similarly, the structure disclosed in "An Integrated Corner Unit Device" (CN217974979 U) also requires that the middle connector be cut when the included angle of the two horizontal beams is acute, so that it can be inserted into the inner cavity of the horizontal beam and fixed to the middle column.

[0004] Therefore, it can be seen that existing corner connectors mainly have the following two problems:

[0005] High customization costs: Given that the corner angles of different building projects often vary, traditional corner connectors typically require customized production based on the specific corner angle. This customized production model not only significantly increases production costs but also extends the production cycle, making it difficult to quickly respond to market demands and hindering the efficient development of the construction industry.

[0006] Limited installation flexibility: Fixed-angle corner connectors require high precision in dimensions and angles at the corners during installation. Any deviation between the actual site conditions and the preset angle can easily lead to installation difficulties or even make installation impossible. This significantly reduces installation flexibility and efficiency, consequently impacting the overall construction progress.

[0007] In summary, the problems faced by existing corner connectors have become an important direction for our further improvement and research, in order to better adapt to the development needs of modern architecture, reduce construction costs, and improve construction efficiency. Summary of the Invention

[0008] The purpose of this utility model is to provide a corner connection system for curtain wall mullions and beams. Through structural improvements, the adaptability of the connectors is effectively improved, material costs are reduced, and construction efficiency is increased.

[0009] To achieve the above objectives, the technical solution adopted by this utility model is: a curtain wall column and beam corner connection system, including a beam and a column, which are fixed by a connecting component. The connecting component includes a tubular base disposed in the inner cavity of the beam. The base includes a first plane fixed to the side of the column, a second plane fixed to the side of the beam, and an arc-shaped tube wall connecting the two planes. The two are respectively fixed to the corresponding side by screws. The first plane is provided with stud holes that penetrate the column and fix the beam to the opposite side.

[0010] In the above technical solution, a pair of slots are provided on the open end face of the front end of the column, respectively located on both sides of the middle support. The left and right slots are respectively connected to the glass panels on both sides through a support rod. A structural adhesive strip is provided between the end of the support rod and the glass panel.

[0011] In the above technical solution, the support at the open end of the column extends to the angle between the two glass panels and is fixed to the outer cover plate by studs. The two sides of the cover plate are respectively abutted against the outer surface of the glass panel by structural adhesive strips.

[0012] A further technical solution is that a spare sleeve is fitted on the stud, one end of which is connected to the slot at the front end of the support, and the other end abuts against the back side of the cover plate.

[0013] In the above technical solution, the base is a semi-open cylindrical tube, one end face of which is the second plane and is fixed to the crossbeam by self-tapping screws, and the other end face is an open opening. The first plane is set on the outer edge surface of the cylindrical base, and the tube wall opposite to the first plane is an opening. A rubber pad is provided between the first plane and the column.

[0014] In the above technical solution, according to the size of the included angle between the two crossbeams on the corner, the connection position between the crossbeam and the column is offset along the surface of the column. The first plane of the base is in contact with the surface of the column, and is fixedly connected by studs from the bolt assembly hole of the base in one side of the crossbeam through the column to the stud hole in the base in the other side of the crossbeam.

[0015] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0016] 1. In this utility model, the connecting component uses a base composed of two arc-shaped pipe walls and a first and a second plane as the connecting body. During installation, the base is inserted into the inner cavity of the crossbeam, and the first and second planes are fixed to the column and the crossbeam respectively. Due to the change in the base structure, compared with the previous connecting parts, there is no need to customize the connecting parts according to the included angle. The base can be fixed as long as it can be inserted into the inner cavity of the crossbeam, which improves the flexibility of the connecting parts, avoids the customization of multiple sizes, and reduces material costs.

[0017] 2. The front end of the column is equipped with a support rod to support the glass panel, replacing the previous column sub-frame structure. It can adapt to changes in the included angle, eliminates the need to consider the customization of the sub-frame, shortens the construction period, and further reduces costs.

[0018] 3. The support at the front end of the column extends to the junction of the glass panels on both sides. The outer side of the glass panel is closed by a cover plate and fixed to the support by studs. The studs are fitted with spare sleeves. The sealing position of the cover plate and the glass panel is adjusted according to the size of the angle. The connection between the cover plate and the support is made with spare sleeves to adapt to different angle requirements, achieve the purpose of unified installation at multiple angles, simplify construction and reduce costs.

[0024] The following description is merely a preferred embodiment of the present invention and is not intended to limit the scope of the present invention. Furthermore, the terms "vertical," "horizontal," "top," "bottom," "front," "rear," "upper," "lower," "inner," and "outer" used in the embodiments of the present invention indicate orientation or positional relationships based on the appendix. Figure 1 The orientations or positional relationships shown, or the orientations or positional relationships in which the product is usually placed during use, are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. This utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] Example 1: See Figures 1-4 As shown, a curtain wall column and beam corner connection system includes a beam 1 and a column 2, which are fixed together by a connecting assembly 3. The connecting assembly 3 includes a tubular base 4 disposed within the inner cavity of the beam. The base 4 includes a first plane 5 fixed to the side of the column 2, a second plane 6 fixed to the side of the beam 1, and an arc-shaped tube wall 7 connecting the two planes. Both are fixed to their respective sides by screws 8. The first plane 5 has stud holes 23 that penetrate the column 2 and fix it to the opposite beam 1. The beams 1 on both sides of the column 2 are mutually restrained by through bolt assemblies 9 to ensure the relative stability of the corner system.

[0026] like Figure 1 , 4 As shown, the front end face of the column 2 has a pair of slots 10, located on both sides of the intermediate support 11. The left and right slots 10 are connected to the glass panels 13 on both sides by a support rod 12. A structural adhesive strip 16 is provided between the end of the support rod 12 and the glass panel 13. By connecting the support rods 12, the previous column sub-frame is replaced, which can adapt to the need for changes in the installation position of the glass panel 13 when the corner size changes, making the installation more flexible.

[0027] The support 11 at the open end of the column 2 extends to the angle between the two glass panels 13 and is fixed to the outer cover plate 15 by studs 14. The cover plate 15 is secured to the outer surface of the glass panel 13 by structural adhesive strips 16 on both sides. A decorative cover 17 can also be clipped onto the cover plate 15. The cover plate 15 has a locking groove 18, and the decorative cover 17 has a protrusion 19. The two engage to conceal the studs 14 and the cover plate 15, improving aesthetics and waterproofing. Figure 1 Or as shown in Figure 4.

[0028] To better facilitate the connection between the stud 14 and the column support 11, a spare sleeve 20 is fitted onto the stud 14. One end of the spare sleeve 20 is inserted into the slot at the front end of the support 11, and the other end abuts against the back of the cover plate 15. Due to the change in angle, the distance between the glass panels 13 on both sides and the support 11 varies slightly, resulting in different length positions of the cover plate 15 when fixed by the stud 14. The spare sleeve 20 is used to adjust and compensate for these differences, achieving a more ideal installation effect.

[0029] like Figure 2 , 3 As shown, the base 4 is a semi-open cylindrical tube, one end of which is the second plane 6, which is fixed to the crossbeam 1 by self-tapping screws. The other end is an open opening. The first plane 5 is set on the outer edge of the tubular base 4. The tube wall opposite to the first plane 5 is an opening 21. The opening 21 is used to fix the first plane 5 to the column 2. A rubber pad 22 or a buffer pad is provided between the two to strengthen the fastening force.

[0030] During installation, the connection position between the crossbeam 1 and the column 2 is offset along the surface of the column according to the included angle between the two sides of the corner crossbeam 1. See [reference needed]. Figure 1 and Figure 4 The first plane 5 of the base 4 is attached to the surface of the column 2, and is fixedly connected by bolt assembly 9 from the stud hole 23 of the base 4 inside the crossbeam 1 on one side through the column 2 to the stud hole 23 of the base 4 inside the crossbeam 1 on the other side.

[0031] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
